[PATCH v4 0/3] Add reset deassertion for Aspeed MDIO

[Dylan Hung]

Add missing reset deassertion for Aspeed MDIO bus controller. The reset
is asserted by the hardware when power-on so the driver only needs to
deassert it. To be able to work with the old DT blobs, the reset is
optional since it may be deasserted by the bootloader or the previous
kernel.

V4:
- use ASPEED_RESET_MII instead of hardcoding in dt-binding example

V3:
- remove reset property from the required list of the device tree
  bindings
- remove "Cc: stable@xxxxxxxxxxxxxxx" from the commit messages
- add more description in the commit message of the dt-binding

V2:
- add reset property in the device tree bindings
- add reset assertion in the error path and driver remove
